Pros and Cons of Selenium In
Automation Testing: A Comprehensive
Assessment
Introduction
In the world of web app development, many organizations, just like yours, trust
Selenium for automated testing. It's a robust tool, widely appreciated for its
power and versatility, making it a top pick. However, let's be real – every tool
has its quirks.
This blog takes a genuine look at Selenium, weighing its pros and cons while
providing a balanced perspective on its strengths and limitations, just like any
good conversation about tech tools should.
What Is Selenium and How It Works
Imagine it's May 2013, and Selenium steps into the spotlight, making waves as
a standout test automation tool. But let's rewind a bit – in 2004, Jason
Huggins was weaving the magic at ThoughtWorks, laying the groundwork for
this incredible tool. That's Selenium for you – a powerhouse in the world of
test automation, born from a history of dedication and innovation.
Selenium serves as a web automation tool, and while it is widely recognized
for its utility in testing, it's not confined to that sole purpose. Beyond testing,
Selenium offers versatility, allowing users to automate various repetitive
administrative tasks that may occur on a weekly basis.
Selenium is available in two primary variations: Selenium WebDriver and
Selenium IDE. The WebDriver version presents a robust framework, enabling
programmable interactions through multiple programming languages. On the
other hand, Selenium IDE operates as a browser extension, facilitating
record-and-playback testing for streamlined automation.
Selenium Suite Development Overview
The Selenium suite, originating with Selenium Remote Control (now Selenium
1), witnessed evolution with its merge into WebDriver, leading to Selenium 2.
However, due to limitations, Selenium RC was deprecated. In 2016, Selenium 3
was introduced, relocating Selenium RC to a legacy package while enhancing
support for browsers and mobile testing. The latest release, Selenium 4 (beta
in February 2021), brought refreshed documentation and server rewrites,
introducing features like relative locators and transitioning to WebDriver W3C
protocol.
Key Components of Selenium Suite
‍
1. Selenium WebDriver (Selenium 4)
● Predominantly synonymous with Selenium, WebDriver is the primary
focus of development.
● Test automation in WebDriver is akin to taxi driving, involving a tester
(customer), WebDriver (taxi driver), and the browser (car).
● Commands are issued to interact with elements, facilitating seamless
communication between the tester and the browser.
‍
2. Selenium IDE
● A Firefox add-on primarily for prototyping, dismissed by some but
embraced by others.
● Suited for learning and simple tasks, IDE records browser actions for
easy replication.
● Despite being non-production-oriented, IDE can be enhanced with
plugins for more robust functionalities.
‍
3. Selenium Grid
● Enables parallel testing on multiple machines and browsers
concurrently, significantly saving time.
● Ideal for large-scale testing, Grid allows configurations with different
browser versions and operating systems.
● Particularly beneficial in production environments for efficient and
time-effective test execution.
Why Selenium Finds Utility in Testing?
Selenium is widely embraced for its capability to facilitate automated testing.
The rationale behind opting for automated testing lies in the complexity of
software, which is susceptible to regressions when new features or defect
fixes are introduced. Conducting exhaustive manual testing after each minor
change becomes impractical. Selenium testing, in particular, enables
organizations to replicate user interactions with their web applications,
ensuring robust testing across various browsers.
Advantages of Selenium Automation
Testing
● Language Agnostic: Selenium WebDriver offers native bindings for
JavaScript, Python, Java, C#, and Ruby, eliminating the need to learn a
new programming language solely for testing. While Selenium has its
syntax, having proficiency in one of these languages proves
beneficial.
● Cross-Browser Compatibility: Selenium communicates with browsers
through drivers and is adaptable to different browser versions. With
the appropriate driver, Selenium seamlessly supports significant
browsers like Chrome, Firefox, Safari, Edge, and Opera.
● Cross-Platform Compatibility: Extending its versatility, Selenium is
cross-platform compatible, allowing test creation on one platform
and execution on another. It effortlessly functions across Windows,
Mac OS, and various Linux distributions.
● Community Support: As an open-source tool with a substantial
history, Selenium boasts a strong community. This support extends
beyond regular updates and upgrades to encompass comprehensive
documentation and a wealth of learning resources.
● Integrations with Third Parties: Selenium excels in integrations,
providing the flexibility to extend functionality through third-party
plugins. Users can leverage existing plugins or create custom ones to
enhance Selenium's capabilities.
● Parallel Test Execution: Selenium supports parallel test execution
across multiple machines, facilitated by Selenium Grid. This feature
enables users to conduct tests simultaneously on various browsers
and platforms, centralizing the management of browser
configurations.
Drawbacks of Selenium Automation
Testing
● High Test Maintenance: Selenium often leads to fragile tests because
it relies on strict element identifiers. Changes to the application,
particularly to element identifiers, can result in test failures, requiring
diagnosis, test fixes, and reruns. Selenium's wait capabilities offer a
solution for rendering issues, but changes to element identification
pose challenges.
● Learning Curve: Despite its power, mastering Selenium is no easy
feat, making it less favorable for teams seeking testing tools without
extensive coding requirements. Selenium IDE, a simpler alternative, is
limited as it's available only as a Chrome and Firefox extension and
needs robust testing features, leading to brittle tests.
● No Built-in Capabilities: Selenium lacks native reporting capabilities,
hindering its ability to provide compelling visualizations for effective
communication, particularly to business and non-technical
stakeholders. Reporting is crucial for assessing release readiness.
● No Reliable Tech Support: While Selenium benefits from a supportive
community, more reliable technical support must be needed. There
may need to be more than the reliance on community assistance to
resolve critical issues promptly.
● Total Cost of Ownership (TCO) is High: Although Selenium is
open-source, the total cost of ownership can be high. Factors like the
learning curve, lack of technical support, the need for additional tools,
and other issues contribute to a substantial TCO. The opportunity
cost, in terms of time spent on test creation instead of application
improvement, adds to the overall expenses.
